A draw press comprises a die-stock coupled to a slide movable perpendicularly to the axis of the press between two operational positions. In a first position, the die-stock is placed on the axis of the press, and in a second position the die-stock is spaced laterally from the axis in a changing device. The latter includes a table contiguous with a bed of the press and a movable carriage for supporting a replacement die-stock, spaced laterally from the axis of the press, and movable on the table in a direction parallel to the axis between a rest position and a position for coupling the replacement die-stock to the slide. The disengagement of the die-stock in position on the slide is caused by movement of the carriage from the rest position to the coupling position. The die-stock changing device includes means for sliding the disengaged die-stock along the carriage and means for fixing the die-stocks relative to the carriage.
